Software analyses nano/micro surface
data
Software released for the analysis of micro- and nano-geometry and 2D/3D surface texture includes a full set of 3D parameters conforming to the new ISO standard on areal surface texture.
Digital Surf has announced the release of version 4.1 of its Mountains technology for the analysis of micro- and nano-geometry and 2D/3D surface texture, and the simultaneous release of its MountainsMap software product line which is based upon this technology Running under Windows, Mountains has been continuously evolved by Digital Surf's team of professional metrologists and software engineers for over 15 years to assure conformity with current and forthcoming standards and methods

Compact imaging system attracts 1600 unit order
The new AV1200 imaging system from Accu-Sort offers versatile, high speed reading or decoding of linear and 2D codes on flat work and cartons within a depth of field of 50mm.
Software based upon Mountains technology is integrated by leading surface metrology instrument manufacturers and used in thousands of research laboratories and industrial facilities worldwide.
The new version includes a full set of 3D parameters conforming to the new ISO standard on areal surface texture scheduled for publication this year, together with over forty new features that provide more powerful analysis of 2D/3D surfaces and facilitate understanding of the functional role of surface characteristics.
Several new metrological functions are based upon segmentation by watersheds, a method for dividing a surface into functionally significant structures only.

Vision CMM has no wiring or mechanical links
Based on innovative vision technology, a portable CMM has neither wires nor mechanical links between its lightweight probe and its measurement device to measure small and large components.
3D motifs analysis segments a surface into significant hill or dale motifs and locates their peaks or pits, making it easier to understand their functional role.
Binary segmentation of motifs provides improved separation of grains and particles, especially when the background is not flat.
A partition levelling operator levels a surface with respect to a selected motif or motifs and facilitates working with geometrical surfaces, for example on MEMS and other mechanical and electronic components.
The segmentation method is also used for determining which peaks are significant for the calculation of the new ISO 3D parameters.
SPM-specific features include flexible loading of multi-layer files, the ability to overlay a texture (SPM layer, image, set of measurement data) on a 3D image of the surface under study, and the definition of SPM-specific measurement axes.
Other new features include a Hanning window function that makes it possible to detect smaller spectral structures and to improve texture direction results, the robust Gaussian filter for 2D and 3D data (with a mean contour that follows profile(s) and is less perturbed by local peaks and valleys), and the graphical study of volume parameters that are typically used in tribological studies.
3D parameters conforming to the new ISO standard include amplitude, spatial, hybrid and volume parameters.
For compatibility with previous versions of the software, there is an option for working with the old European Surfstand and Birmingham 14 3D parameters.
Users of MountainsMap 4.0 benefit from an upgrade path to MountainsMap 4.1.
